You .htaccess is different from the original one. So it could be possible that you have an old version, a completely different, ... so that could be a reason for your problem.
Regarding you logfiles, it would be interesting to see the owncloud and webserver logfile around the moment when the error occurs.

Hello and thank you for your answer.

About the .htaccess, I've made 2 different installation and the same problem happened. Maybe virtualmin is replacing the .htaccess I don't know.

For the apache log, I've got no error juste this in the access log :
46.253.189.93 - - [06/Sep/2016:10:25:35 +0200] "PROPFIND /remote.php/webdav/ HTTP/1.1" 401 306 "-" "Mozilla/5.0 (Windows) mirall/2.2.3 (build 6307)"

I the ownCloud log, I don't see anything. The last log is from yesterday and here are the 3 last lines.
{"reqId":"V80jjAihQ9e4sJuUdFJBbAAAAAc","remoteAddr":"46.253.189.93","app":"core","message":"Login failed: 'Anywen' (Remote IP: '46.253.189.93')","level":2,"time":"2016-09-05T07:49:32+00:00","method":"POST","url":"\/index.php\/login","user":"--"}

{"reqId":"V80jjAihQ9e4sJuUdFJBbQAAAAc","remoteAddr":"46.253.189.93","app":"PHP","message":"Invalid argument supplied for foreach() at \/home\/anywen\/domains\/cloud.anywen.ch\/public_html\/core\/templates\/login.php#23","level":3,"time":"2016-09-05T07:49:33+00:00","method":"GET","url":"\/index.php\/login?user=Anywen","user":"--"}

is the .htaccess file a generic file that is pretty much the same on every installation ? How could I get a good one ?

edit : here is the htaccess file in my folder, if it can help
https://cloud.anywen.ch/index.php/s/D9Ki3fB9YTDQ05z

No, that's no the right one. You can download the archive of every OC version on https://owncloud.org/changelog
Use the .htaccess from this archive.

So, I changed the htaccess and everything is working fine now.

Thank you !
